13. Chemical cuticular signature of leafcutter ant Atta sexdens (Hymenoptera, Formicidae) worker subcastes
ABSTRACT In leafcutter ants the division of labour is associated to worker size variation clustered in four subcastes. In this work we used Atta sexdens Forel (1908) as a model to test the hypothesis that each subcaste expresses its own chemical signature comprised of cuticular lipids. To assess it, we extracted epicuticular compounds by using nonpolar solve

14. New species of the stingless bee genus Schwarziana (Hymenoptera, Apidae)
ABSTRACT Two new species of the stingless bee genus Schwarziana from Brazil are described and illustrated. Schwarziana bocainensis sp. nov. is described from Serra da Bocaina, in São Paulo, and S. chapadensis sp. nov. is described from Chapada dos Veadeiros, in Goiás. An identification key to workers of the known species of Schwarziana is provided.

15. Venomous and poisonous arthropods: identification, clinical manifestations of envenomation, and treatments used in human injuries
Abstract This review presents the main species of venomous and poisonous arthropods, with commentary on the clinical manifestations provoked by the toxins and therapeutic measures used to treat human envenomations. The groups of arthopods discussed include the class Arachnida (spiders and scorpions, which are responsible for many injuries reported worldwide,

16. Notes on social wasps of the group of Mischocyttarus(Omega) punctatus (Ducke), with description of six new species (Hymenoptera, Vespidae, Polistinae)
ABSTRACTA revision of the taxonomic status and an identification key for wasp species of the genus Mischocyttarus related to M. punctatus (Ducke, 1904) are presented here. Six new species are proposed (M. tayrona Silveira sp. nov.; M. anchicaya Silveira sp. nov.; M. caxiuana Silveira sp. nov.; M. verissimoi Silveira sp. nov.; M. rodriguesi Silveira sp. nov.;

17. Is the capture success of orchid bees (Hymenoptera, Apoidea) influenced by different baited trap designs? A case study from southern Brazil
Orchid bees are increasingly applied on Neotropical biomonitoring and bioindication studies due to the relative easiness of sampling and identification when compared to other bee groups. A considerable number of orchid bee community studies have been adopting baited traps as a sampling method, especially for replication purposes. However, the trap attributes

18. Notes on the systematics of the orchid-bee genus Eulaema (Hymenoptera, Apidae)
Notes on the systematics of the orchid-bee genus Eulaema (Hymenoptera, Apidae). The classification of the genus Eulaema is modified in order to make it congruent with recent phylogenetic hypotheses based on molecular data. The speciosa group, containing E. peruviana, E. speciosa and related species, is removed from E. (Eulaema) and transferred to E. (Apeulae

19. Prey identification in nests of the potter wasp Hypodynerus andeus (Packard) (Hymenoptera, Vespidae, Eumeninae) using DNA barcodes
Prey identification in nests of the potter wasp Hypodynerus andeus (Packard) (Hymenoptera, Vespidae, Eumeninae) using DNA barcodes. Geometrid larvae are the only prey known for larvae of the Neotropical potter wasp Hypodynerus andeus (Packard, 1869) (Hymenoptera, Vespidae, Eumeninae) in the coastal valleys of the northern Chilean Atacama Desert. A fragment o

20. Revision of the Neotropical Laelius (Hymenoptera: Bethylidae) with notes on some Nearctic species
Laelius Ashmead includes 54 known nominal species worldwide. We present a revision of the Neotropical species of Laelius and provide keys for the identification of males and females of these species. We propose fourteen nomenclatural changes and additions. For the Neotropics, seven new species from Brazil are described and illustrated: Laelius arryni sp. nov

21. Social wasp species of Mischocyttarus (Phi) related to M. alfkenii (Ducke) and M. paraguayensis Zikán (Hymenoptera, Vespidae, Polistinae)
Social wasp species of Mischocyttarus (Phi) related to M. alfkenii (Ducke) and M. paraguayensis Zikán (Hymenoptera, Vespidae, Polistinae). A revision of the taxonomic status and an identification key are presented for species of the genus Mischocyttarus related to M. alfkenii (Ducke) and M. paraguayensis Zikán. Seven new species are proposed in the alfkeni

22. Ant species (Hymenoptera, Formicidae) from the seasonally dry tropical forest of northeastern Brazil: a compilation from field surveys in Bahia and literature records
Ant species (Hymenoptera, Formicidae) from the seasonally dry tropical forest of northeastern Brazil: a compilation from field surveys in Bahia and literature records. The Caatingas occur predominantly in northeastern Brazil and comparatively it is the biome that received less attention than any other ecosystem in Brazil, representing the region where invert

23. Explorando as interações hospedeiro-parasitoide para a identificação de moléculas com potencial biotecnológico / Exploiting the host parasitoid interactions for the identification of molecules with biotechnological potential
Parasitoides criam condições favoráveis para seu desenvolvimento regulando processos fisiológicos do hospedeiro via a utilização de moléculas produzidas por tecidos maternos ou por tecidos derivados do parasitoide imaturo ou de simbiontes associados (vírus de poliDNA - PDV). Assim, essas moléculas se destacam como uma fonte preciosa para o desenvolv
